Arnold Schoenberg

Arnold Schoenberg (1874-1951) was an Austrian composer and teacher, born in Vienna. He moved from late Romanticism into free atonality and in 1923 announced his method of composing with twelve tones related only to one another. With his students Alban Berg and Anton Webern he formed the core of what became known as the Second Viennese School. Schoenberg wrote Pierrot lunaire, Op. 21, in 1912. He taught privately in Vienna and from 1926 led a composition master class at the Prussian Academy of Arts in Berlin.
